Specification of Letters Patent. 7 Application filed November 9,1905.Serial No. 286.625.

To all whom it may concern.-

Be it known that I, LEWIS J. JoHNsoN, a citizen of the United States,residing at Springbay, in the county of Woodford; and

State of Illinois, have invented certain new and useful Improvements inGrain-Renovators ,"and I do declare the following to be a full, clear,and exact description plfltlhg inve}I11- ers s i e in t e' tion; such aswill enable ot art to which is appertains to make and use the same.

This invention relates to im rovements in devicesfor renovating and cooing grain.

The object of the invention is'to provide a simple, convenient, andefficient portable device which may be readily inserted in the grain ina bin, crib, boat, car, warehouse, or other container in order to permitcurrents of air or other cooling or fumigating gases to be forcedthrough the grain to cool or renovatethe same.

The above and other objects are accomplished by the constructionillustrated in the accompanying drawings, in which- Figure 1 is asideelevation with arts in section of an apparatus constructe inaccordance with my invention, and Fig. 2 is a to plan view of the same.

iteferring to the drawings by numeral, 1 denotes a pipe or tube, eitherflexible or rigid, through which cooling and renovating currents of airor other gases are adapted to be forced b a pump or any other suitableapparatus. his pipe opens into a distributinghead 2, which is here shownin the form of a circular tube or pipe, but which may be of Ianyrojecting from the distributer 2, is a pluralit of discharge pipes ortubes 3, which have t eir lower or outer ends closed and formed for ashort distance from said ends with series of slits or perforations 4.Slidably mounted upon the said'ends of the pipes 2 are perfo ratedcasings5, which are preferably in the form of cylindrical tubes or pipesinto which the pipes 3 telescope. The pipes or casings 5 have tapered orpointed lower ends 6 to permit them to be readily forced'into the grain,and their upper ends are closed by heads 7, through centrally-disposedopenings in which the pipes 3 slide. Thepipes or casings 5 may besecured in any adjusted position upon the pipes 3 in any suitablemanner. As shown, I

have provided set-screws 8 for this These set-screws pass throughthreaded openings in the heads? and are adapted to engage the pipes 3.

If desired, I may provide upon the pipes 3,

ower

atthe inner ends-of their erforated portion, circular heads 9, w "chslide in the pipes or-casings 5 and prevent thedischarge ofair into theportions of said pip'esor'casings above said heads.

i The use and advantages of the invention willl be readily seen. Whenitis desired to coo Patentedilarch 5,1907. 7 I

purpose. I

a bin, crib," boat, car, warehouse, or other container, the casings 5are driven into the grain, the points 6 facilitating this operation.

The pipes 3 are then adjusted in the pipes or casings 5, or, if desired,they maybe adjusted beforehand,- so that air or other gas dischargedthrough the pipes .1, 2, and 3 will pass through the slits orperforations 4 in the ower ends of the pipes 3, then through theperforations in the casings or pi es 5, and then pass through the grainto coo and renovate 1t. By providing the heads 9 upon the pipes 3 andadjusting the latter in the casings or pipes 5 so that said heads areabout on a level with the level of the grain into which the apparatusisinserted all of the air or gas will be caused to be discharged intoand through the grain.

From the foregoing description, taken in connection with theaccompanying drawings, the operation and advantages of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention.

. Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- 1 1.- The herein-describedgrain-renovating apparatus comprising the distributor-head, the pipedischarging thereinto, the dischargepipes projecting from thedistributer-head, the perforated cylindrical casings having the conicallower portions and the heads at their upper-ends, said heads havingopenings in which the discharge-pipes are slidable and provided withclamping means to secure the p '5 fumigate, or otherwise treatth' graihsaid pipes therein, said' casings being adglst able on saiddischarge-p1pes toward and om n said distributer-head.

2. The herein-described grain-renovating apparatus comprising theperforated casings having the tapered lower ends, theheads and theclamping-screws, and the distributer head having the pipe dischargingthereinto and the discharge-pipes proj ecting therefrom, saiddischarge-pipe extending through the heads of the casings, slidable insaid heads,

Masai entering the casings and-having the heads movable in said casings,substantially as de scribed.

In testimony whereof I have hereunto set i 5 my hand in presence of twosubscribing Wit- I nesses. 3
